REPAIR-TOOL FOR PNEUMATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 622,37*?, dated April4, 1899. Application l'ed February 21, 1899. Serial No. 706,426. (Nomodel.)

To all whom it may concern:

Be it known that I, HOWARD C. MARCH, acitizen of the United States,residing at Port-A age, in the county of Wood and State of Ohio, haveinvented certain new and useful Improvements in Repair-Tools forPneumatic. Tires; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use'the same. i

My invention relates to improvements in re pair-tools for bicycles, andmore particularly to that class employed in repairing punctures inpneumatic tires; and the object is to provide a simple, inexpensive, andeffective, as well as convenient, device for this purpose.

Vith this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter morefully described and claimed.

In the accompanying drawings, Figure 1 is an enlarged perspective viewof my improved pneumatic-tube-repair tool. Fig. 2 is a similar viewshowing the members separated. Fig. 3 is a longitudinal section with thecement-tube inserted in the puncture-tool. Fig. 4 is a cross-section onthe line 4 4 Of Fig. 3. Fig. 5 shows a rubber band in position on thetool and ready for insertion in the tire.

1 denotes a sleeve or tube having its sur= face milled or knurled, asshown, toform a handle for convenience in manipulation, and 2 denotes acollar orflange formed with two ra'dial notches 3 3.

4and 5 denote longitudinal spring-jaws, the tension of which is exertedto spring their free ends together. The jaws 4terminate in a point .6,behind which is a rabbeted recess or shoulder '7 to receive thecorrespondinglyshaped free end of the jaw 5.

8 denotes a recess or notch formed in the inner face of the jaw 4, andbehind this is a teat or tooth 9, which extends into a longitudinalgroove 10, formed in the meeting face of the jaw 5. 12 denotes thecement-tube, which is provided with a threaded socket 13 to receive thecorrespondingly-threaded. neck of the usual collapsiblecement-dispensing tube 14. A longitudinal groove 15 is also formed inthe inner face of the arm 4, so that where the tube 12 is insertedbetween the jaws these grooves 10 15 form a guide for said The manner ofusing the tool is as follows The tube 12 is inserted through the sleeve1,

and as it is pressed forward it separates the spring-jaws 4 and 5, asshown in Fig. 3. The looped 'end of a small rubber band is then placedin the notch or recess 8 in the arm 4, and the tube 12 is then withdrawnand the arm 5 clQSsQQWnaHSQQlI/Resthelaopednend f the rubber band inlace. The opposite wlmw stretched backward through the radial notches 33 in the collar and its end passed over the'sleeve 1, the tension of therubber drawing the band down around the sleeve and collar, as shown inFig. 5, which retains it in place. The point 6 of the tool is nowinserted through the puncture in the tire, carrying with it the forwardend of the rubber band. The rear end of the band is now released orthrown off from the collar, so asto hang loose. The tube 12 is againinserted between the jaws to separate them and release the forwardend ofthe Vrubber band, which is now within the tire. The collapsiblecement-tube is now connected to the socket 13 and a suflicient amount ofcement forced in the tire to cement the band in place. The tool is nowwithdrawn from the tire, which closes about the cemented band andhermetically seals the puncture.

The accompanying drawings show my invention in the best form now knownto me;

but many changes in the details might be made within the skill of a goodmechanic without departing from the spirit of my invention as set forthin the claim at the end of this specification.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s

Ina repair-tool of the class described, the sleeve provided with thenotched collar, and the parallel spring-arms, one of which is formedwith a retaining-recess, and a pointed' end in combination with the tube12, adapted to be inserted in said sleeve, and between said arms tospring them apart, substantially as and for the purpose set forth. l

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
